I have a garden seat at the bottom of the garden in a sunny spot. It
has jasmine behind it and now the blackbirds have left the nest in the jasmine, I want to repair it.
The base is on paving slabs and is straight, but the trellis arch thing over the top (all attached) has a distinct lean. Its not a case of straightening the whole thing but just to pull it upright. I'm thinking some kind of wood to brace it straight???
How do i do this? I think its a maths problem
